How much do assays jobs pay per year?

As of Jun 6, 2026, the average yearly pay for assays in the United States is $70,647.00, according to ZipRecruiter salary data. Most workers in this role earn between $51,500.00 and $83,000.00 per year, depending on experience, location, and employer.

What are assays?

Assays are laboratory procedures used to measure the presence, amount, or activity of a specific substance—such as a chemical, cell, or biomolecule—in a sample. They are essential in fields like biochemistry, pharmacology, and medical diagnostics to evaluate the efficacy of drugs, detect diseases, or analyze biological processes. There are many types of assays, including bioassays, immunoassays, and chemical assays, each tailored to different analytical needs. Researchers select the appropriate assay based on the target substance and the required sensitivity and specificity.

What are some common challenges faced by professionals working in assay development and how can they be addressed?

Professionals in assay development often encounter challenges such as optimizing assay sensitivity and specificity, troubleshooting inconsistent results, and adapting protocols for high-throughput environments. These challenges can be addressed by staying current with best practices, collaborating closely with cross-functional teams such as R&D and quality assurance, and rigorously validating each step of the assay process. Open communication, thorough documentation, and continuous training also play key roles in ensuring successful assay development and execution.

What is the difference between Assays vs Laboratory Technicians?

AspectAssaysLaboratory Technicians
Required CredentialsTypically requires a degree in biology, chemistry, or related field; certifications may be preferredUsually requires an associate degree or certification in laboratory procedures
Work EnvironmentConducts specific tests and assays in labs, often in research or quality control settingsPerforms routine lab tasks, prepares samples, and maintains lab equipment
Industry UsageCommonly used in biotech, pharmaceuticals, and research labs for testing and analysisWidely used across healthcare, clinical, and industrial laboratories

Assays focus on performing specific tests to analyze samples, often requiring specialized knowledge of testing protocols. Laboratory Technicians handle a broader range of lab tasks, including sample preparation and equipment maintenance. While both roles work in lab environments, assays are more specialized in testing procedures, whereas technicians support overall lab operations.

What are the key skills and qualifications needed to thrive as an Assay Specialist, and why are they important?

To thrive as an Assay Specialist, you need a solid background in biochemistry or molecular biology, laboratory techniques, and data analysis, usually supported by a relevant science degree. Familiarity with laboratory information management systems (LIMS), PCR machines, spectrophotometers, and quality control procedures is typically required. Strong attention to detail, problem-solving skills, and effective communication set top performers apart in this role. These competencies are crucial for ensuring accurate test results, maintaining data integrity, and supporting scientific research or diagnostic outcomes.

Job description

Legend Biotech is seeking a Scientist II, Analytical Development, Gene Editing and Molecular Assays as part of the Technical Development team based in Somerset, NJ.

Role Overview

This position will be responsible for developing analytical methods and performing QC and in process sample testing to support the manufacture and characterization of Legend's gene and cellular therapy pipeline and first-in-human/new IND products. The individual will be responsible for analytical methods development, qualification and internal or external transfer; routine testing of final product (GMP), stability, and in-process samples; and performing data review and verification, lab and instrument maintenance etc. The position will be responsible for maintaining accurate and contemporaneous records in a lab notebook and reporting results in a timely manner.

Key Responsibilities

  • Develop, optimize and qualify molecular biology methods for parameters such as: VCN, gene editing proficiency, infectious titer, genomic titer, rapid mycoplasma, surrogate RCL, residual DNA, etc.
  • Subject matter expert supporting routine testing of final product (GMP), stability, and in-process.
  • Perform review of testing data (e.g., data packets, final lot file, COA review).
  • Perform data verification, data review and review of GMP documentation for multiple methods (general and complex) and/or products.
  • Cross trained in multiple complex analytical methods and/or multiple products.
  • Train others on multiple QC test methods, processes and procedures.
  • Author and review/ revise technical documents such as test methods, SOPs, specifications, trend reports and/or sample plans as appropriate.
  • Maintain accurate and updated lab notebooks.
  • Manage equipment and records for maintenance, calibration and operation. Contribute to maintenance of laboratory inventories.
  • Procure and qualify required materials to perform experiments or testing.
  • Work collaboratively with members of Analytical Development team to establish the analytical control strategy of the established methods.
  • Perform other tasks as assigned.
  • Typically, you have the authority to make decisions related to planning and execution of assay development runs. You can also make decisions related to weekly work priority. Higher-level approvals are required for those related to significant assay development methodology change, strategic shifts, or collaborations with other functional teams.

Requirements

  • BS, MS or Ph.D. in Molecular Biology, Cell Biology, Biochemistry, or a related field.
  • A BS with 6-8 years of significant practical experience; a MS with 4-6 years of hands-on experience in QC testing and method development and qualification of gene and cell therapy products, Vaccine, Antibody, AAV, other Biologics; or a Ph.D. with 1-3 years of assay development experience in pharmaceutical field.
  • Demonstrated experience in assay development and GMP QC testing of Biologicals (e.g., qPCR, dPCR, ddPCR, ELISA, Cell culture and Cell based assays).
  • Ability to accurately and completely understand, follow, interpret and apply Global Regulatory and cGMP requirements.
  • Ability to communicate effectively with peers, department management and cross-functional peers about task status, roadblocks and needs.
  • Advanced ability to work in a fast-paced team environment, meet deadlines, and prioritize work from multiple projects.
  • Advanced knowledge of LIMS, ELN, Veeva, GraphPad Prism, JMP and laboratory data analysis systems preferred.
  • Expertise in analytical method qualification and validation, and tech transfer in In Vivo CAR-T, Vaccine, Antibody, AAV, or other Biologics is plus.
  • Strong communication skills, both written and verbal, with a demonstrated capacity to thrive in collaborative, team-driven environments.
  • Excel, Word, PowerPoint, etc
  • GraphPad Prism, other data analysis tools (PowerBI, JMP, etc)
  • ELN, LabVantage, etc
